Abstract: The invention relates to a device for the thermal tempering of at least parts of the cross section over the lengthwise extension of sequentially produced profiled rolling stock from the rolling heat.

Abstract: A device and a process for tempering at least parts of the cross section of sequentially produced profiled rolling stock from the rolling heat and for the subsequent cooling thereof to room temperature. The device comprises a hardening device comprising at least to liquid cooling devices arranged next to each other and a transport device having rests for the rolling stock that can be moved across the entire hardening device. Thereby the liquid cooling devices can simultaneously and independently be supplied with rolling stock to be hardened.

Abstract: Process and device for hardening a rail. The process for hardening a rail or part thereof by transforming it from an austenitic structure into a different microstructure that is stable at room temperature comprises aligning, horizontally positioning, and fixing in axial alignment to secure against bending, the rail in its austenitic state; and while keeping the rail fixed in axial alignment and secured against bending, force-cooling the rail or part thereof to allow the austenitic structure to be transformed into said different microstructure. The device for hardening a rail or part thereof by force-cooling comprises a support for supporting the rail; a cooling device for force-cooling the rail or part thereof; and at least two fixing devices for axially aligning and securing the rail against bending during the force-cooling.

Abstract: An apparatus for unloading rails from a freight car on which the rails are arrayed to extend in a longitudinal direction of the freight car comprises a track-bound car, and a rail guiding unit positioned at each car end. Each rail guiding unit comprises a pair of rail guide heads having guide rollers for centering a respective one of the rails therebetween. The rail guide heads of a first rail guiding unit are positioned at one of the car ends and are displaceable in a horizontal plane perpendicularly to the longitudinal direction, and drives are provided for vertically adjusting the rail guide heads of the first rail guiding unit.

Abstract: Method for heat-treating profiled rolling stock, including track and railroad rails, having a profiled surface and increased heat removal from portions of the profiled surface during cooling in the gamma range of an iron based alloy material. The method includes aligning the profiled rolling stock, at an average temperature of between 750° C. and 1100° C., straight in its longitudinal direction by plastic shaping, and moving the aligned profiled rolling stock, in its aligned state, in a transverse direction and holding same there. The method also includes evenly cooling of the aligned profiled rolling stock, in a first cooling, to a temperature below 860° C.
